California Science — Grade 4

Comprehensive Course Syllabus

Course Overview

Our California Grade 4 Science course is designed around the California Next Generation Science Standards (CA NGSS). Students explore life science, physical science, earth and space science, and engineering through investigations, models, evidence-based explanations, and design challenges.

Grade 4 places particular emphasis on plant and animal structures, sensory information, energy, waves, electricity, energy transfer, rocks and fossils, Earth’s changing landscapes, and engineering solutions. Students learn science through investigation and evidence rather than memorization alone.

Waves & Communication

Students explore how patterns in waves can be used to communicate information and connect science concepts with everyday technologies.

Module 6

Rocks, Fossils & Changing Earth

Topic 6.1

Rocks & Earth’s History

Students examine rocks as evidence that Earth’s surface has changed over long periods of time.

Topic 6.2

Fossils in Rock Layers

Students investigate fossils found in different rock layers and use their positions and patterns as evidence about Earth’s past.

Topic 6.3

Reading Rock-Layer Evidence

Students compare patterns in rock formations and fossils to develop explanations about how landscapes have changed over time.

Topic 6.4

Changing Landscapes

Students explore evidence that areas can change from land to water or water to land over long periods of time.
